Balanced output and unbalanced output, more options 2.5mm balanced interface connects with balanced headphones to provide more powerful drive, full-balanced circuit to bring a wider sound field and more accurate positioning. Dual DAC, 4-way LPF circuit, 4-way amp circuit, true full-balanced output
Dual output, well designed optimized circuit Using two AK4490 as DAC chip Two MUSE8920 chips as low-pass filter chips The part of headphone amp divided two AD8397, regardless of cost, sophisticated materials, only for seeking more excellent voice performance. Dual crystal oscillator (KDS ~ DSB series)
H24.5OD727 and H22.5OD726 two crystals use the sound source with different sampling rate respectively. Provide clock frequency, the use of Japan's large vacuum imported crystal oscillator. High accuracy, effectively reduce the phase distortion
